Auto Learn
NOTE:
This procedure allows relearning of Passlock™ module or VCM learned data code after replacement of Passlock™ module, Passlock™ sensor or VCM. DTC B3031 will set when entering programming mode.
- Clear all DTCs. See scan tool manufacturer's instructions. Turn ignition off. Replace component(s) as necessary.
- With transmission in Park (A/T) or Neutral (M/T), momentarily turn ignition switch to START position (DO NOT start engine). Leave ignition switch in RUN position (engine off). If Passlock™ sensor was replaced, SECURITY indicator light will flash for 10 minutes. If Passlock™ module was replaced, SECURITY indicator light will flash for a few seconds, then stay on for 10 minutes. If VCM was replaced with a new VCM, vehicle may start and procedure may not be needed. If replacement VCM was used even momentarily, SECURITY indicator light will flash for a few seconds, then stay on for 10 minutes. After 10 minutes, when light turns off, turn ignition switch to OFF position for 10 seconds.
- Repeat step 2 twice more. Auto learn procedure will be completed during next start attempt. Clear all DTCs. If VCM was replaced, reprogram VCM. See appropriate SELF-DIAGNOSTICS article in ENGINE PERFORMANCE.
